Tonsor praesegmen videt.

Tonsor is in the nominative singular, which is the case normally used for the subject of a sentence.

It is a third-declension noun meaning barber. In this sentence, tonsor is the one doing the action of videt, so it is the subject.

Because it is the thing being seen, so it is the direct object of videt.

Its form here is accusative singular. One thing that can confuse learners is that neuter nouns often have the same form in the nominative and accusative singular, and that is true here. So praesegmen could look like either nominative or accusative by form alone, but in this sentence it functions as the object.

A useful rule is:

• neuter nominative singular = neuter accusative singular

So the verb and the sentence structure help you identify its job.

Videt is the verb. Grammatically, it is:

• present tense
• active voice
• indicative mood
• third person singular

So it means he sees, she sees, or it sees, depending on the subject. Since the subject is tonsor, it means the barber sees.

The ending -et here tells you it is third person singular present.

Latin does not have articles like English the and a/an.

So tonsor can mean:

• the barber
• a barber

And praesegmen can mean:

• the clipping
• a clipping

You figure out which is more natural from context.

Latin often likes to place the verb at or near the end of the sentence, although it does not have to.

So Tonsor praesegmen videt follows a very common Latin pattern:

• subject
• object
• verb

But Latin word order is much freer than English word order because the endings give grammatical information. So other orders are possible too, such as:

• Praesegmen tonsor videt
• Videt tonsor praesegmen

These can still mean the same basic thing, though emphasis may change.

Yes, often they could.

Because Latin relies heavily on case endings rather than word order, the roles of the words are usually clear even if the order changes.

For example, these could still mean essentially the same thing:

• Tonsor praesegmen videt
• Praesegmen tonsor videt
• Videt tonsor praesegmen

However, word order in Latin often affects emphasis or style. A word placed first may be more prominent, and a verb placed first can sound more vivid or dramatic.

Tonsor is a third-declension masculine noun.

Its dictionary form is typically given as:

• tonsor, tonsoris = barber

That second form, tonsoris, shows the stem tonsor- / tonsoris and tells you how it declines.

In this sentence, tonsor is nominative singular.

Praesegmen is a third-declension neuter noun.

Its dictionary entry would normally include the genitive, something like:

• praesegmen, praesegminis

That tells you the noun belongs to the third declension and that its stem changes to praesegmin- in many forms.

Because it is neuter, one important rule applies:

• nominative = accusative
• in the plural, nominative plural = accusative plural as well

So its form in this sentence fits well as a neuter direct object.

Latin usually does not need an explicit subject pronoun like he, she, or it if the subject is already clear.

The verb ending in videt already tells you third person singular, and the noun tonsor names who that third person is.

So Latin naturally says:

• Tonsor praesegmen videt

rather than something like He the barber sees the clipping, which would be unnecessary.

A classroom pronunciation might be approximately:

• TON-sor prae-SEG-men WEE-det in a more classical style

A few notes:

• tonsor has stress on the first syllable: TON-sor
• praesegmen has stress on SEG
• videt is pronounced roughly WEE-det in reconstructed classical pronunciation, because Latin v was pronounced like English w

If you are using an ecclesiastical pronunciation, v may sound more like English v instead.

It has the basic parts needed for a full statement:

• a subject: tonsor
• a verb: videt
• a direct object: praesegmen

So grammatically it is a complete sentence meaning that the subject performs an action on the object.

Even though it is short, it is fully complete in Latin.
